Answer:

10\dfrac{1}{2}in^{2}

Step-by-step explanation:

If we solve for the surface area for each of the 14 cubes, we will come up with a surface area larger than the shape. The best way to go around this is to solve for each face of the shape.

The shape has a total of 42 faces.

The volume of a cube is s³, each cube is \dfrac{1}{8}in^{3}or can be converted to (\dfrac{1}{2}in)^{3}. So a single cube have edges that are \dfrac{1}{2}in.

The area of a single face of each cube is (\dfrac{1}{2}in)^{2}. We can also write this as \dfrac{1}{4}in^{2}.

Now that we have the area of a single face in the shape, we simply multiply the area by 42 faces.

Surface Area = \dfrac{1}{4}in^{2} x 42

Surface Area = 10\dfrac{1}{2}in^{2}

What value is true of x makes this equation true 0.7x-5=0.2x+1
Sever21 [200]

Answer:

x=12

Step-by-step explanation:

First you make sure x is on both sides of the equation. So you do 0.7x-5-0.2x=0.2x+1-0.2x. Which just simplifies to 0.5x-5=1. You make sure x is the only thing on that side of the equation so you do 0.5x-5+5=1+5 which simplifies to 0.5x=6. Multiply the equation times 2 to just have x. x=12. The value that makes true of x is 12.
